"Anytime anybody features wings and sells wings, it’s going to take some wings off the market," Sanderson said in a telephone interview today.

Wings in cold storage at the end of July almost doubled to 94.2 million pounds (207 million kilograms) from a year ago, according to the U.S. Department of Agriculture. The Georgia Dock price of wings, a benchmark for the commodity, has dropped 29 percent to $1.44 a pound from a January record, according to the USDA.

It’s difficult to determine how McDonald’s entry into the wings market will affect prices because it’s unclear how much inventory the Oak Brook, Illinois-based restaurant chain holds, Sanderson said. Demand typically rises during the U.S. football season that begins in September and peaks around the Super Bowl championship game.

Sanderson is not a supplier of wings to McDonald’s.
